For researchers who want to make their own soft plastic pieces, we do sell our plastisol. However, we do not provide instructions or an MSDS. The plastisol is "hard" as opposed to "soft." If you want the soft plastisol, please contact us. The price is the same for the hard or soft. For "harder" plastisol, order Hardener which the buyer mixes into the plastisol to get the desired consistency.
